It may have struck many people as odd that Lamar Alexander, the senior senator from Tennessee, gave a shout-out to Alex Haley, the author of The Autobiography of Malcolm X, during his remarks at the presidential inauguration.

"The late Alex Haley, the author of Roots, lived his life by these six words: Find the good and praise it," Alexander said Monday on the National Mall, just before he introduced Justice Sonia Sotomayor, who swore in Vice President Biden. (Alexander was the only Republican lawmaker to speak at President Obama's inauguration.)

"The Tennessee Republican and the celebrated author were good friends. During his second term as governor, Alexander invited Haley to co-chair a homecoming celebration for Tennesseans. During the planning, Haley was convinced to move back to the state. The two once traveled for weeks on a cargo ship together, both working on books. Alexander has called Haley 'the greatest storyteller Tennessee has ever produced.' "
